How the Win10 Edge Browser uses the Web Notes feature

Win10's new Edge browser (formerly known as the Spartan browser) has some interesting new features, such as the Web Notes feature. I believe that everyone is still relatively new to this function, how to use it? And see the analysis below.
Methods
1. On the right side of the address bar, click the button for “Do Web Notes”.

2. In the Web Notes function interface, select the type of subdivision you want to use.

3. When you are done, click the Save button to save to your favorites or read the list.
It should be noted that when opening some websites, the use of Web Notes is not currently supported. If you like it, you can experience it.
